If at First You Don’t Succeed, Revise, Revise Again

I’ve posted a few times about OC COVID-19 results the last few weeks. One of the issues is the data has HUGE (YUGE perhaps?) revisions on the number of tests well after the fact.

Here is a chart showing the number of tests reported by he day I downloaded the data.

OC Testing Numbers by Reporting Date

Now, I get that if I look at data on May 25th, the last couple of days may need revisions. But on May 29th, the data for May 15th (2 weeks!!!) was revised up by 40%.

The same thing happened on May 19th. That data was revised on June 4th, two weeks after the fact.

I have no idea what is going on with these major revisions, but it makes some analyses hard.

OC Covid Data: Still Climbing

Here’s the most updated data on OC testing. Note the data for number of tests was updated for the prior week (surprised the update on testing was so large).

Left Axis: 7-day moving average of new daily cases, Hospitalizations, and ICU patients. Right Axis: Number of tests

As you can see, the number of pretty much everything is at all time highs. Cases came down a little this week.

The next question is: Will Memorial Day festivities bring a surge of cases next week?
